The Edgardo Cadlum Hall, named in honor of Zobel’s longest-serving Principal, Edgardo S. Cadlum (1932–2010), is a testament to architectural evolution and purpose. The ground floor hosts a multi-purpose hall, seamlessly extending into the cafeteria, and also accommodates the school bookstore. Previously the site of the stand-alone Gym 2, this contemporary structure now boasts a dedicated basketball court on its second floor, effectively repurposing the original gym space. The design not only pays homage to its historical function but also caters to the evolving needs of the institution. The hall seamlessly integrates recreation, dining, and learning, representing both tradition and progress.
